My Opera still takes Mails from another account - they're gone

I know that this topic doesn't fit to this category, but I didn't find a better one.

When I came home from work today I was quite shocked and surprised by the shutdown of My Opera Mail, which was my main e-Mail-adress. I have to change a lot of other accounts, inform people,... OK.
But there is another problem: I made opera mail take my e-Mails from an account I have at gmx.net to my opera in-box. I now realised that this still seems to be working - some minutes after I receive a Mail at my gmx-account it's gone, probably because my opera tries to take it to the myopera in-box.
Is there anything I can do about thatß It would be really bad, if I had two "damaged" or lost Mail-Accounts at the same time!

rafaelluik, this link can not retrieve emails, I really have very important emails that need to be recovered, I believe the "Opera" will enable something for at least 1 month to allow your users to retrieve important emails . We have a solution?
